Hello. Unfortunately, this bug is still present on a fully updated Stretch system. I have at-spi2-core 2.22.0-6 installed and constantly experience Orca crashes with exactly the same segfault. This is especially annoying on Gnome when switching windows. With Mate it seems to occur only sometimes when closing some apps like Pluma, but it is still noticeable. Which additional info can I provide to help fixing this bug? Thanks.
